[0046] Example

[0047] Reference Figure 1~Figure 4 , is an embodiment of the utility model, and proposes

[0048] An auxiliary device for increasing the working nodes of a trolley, comprising:

[0049] Handcart assembly 1;

[0050] A supporting plate 2 is used to support the trolley assembly 1, and the supporting plate 2 has a plurality of slide grooves 3;

[0051] The lead screw 4 is rotatably arranged on the supporting plate 2;

[0052] The push plate 5 has an action end 6 and a mounting end 7. The mounting end 7 passes through the slide groove 3 and is threadedly arranged on the lead screw 4. The action end 6 is abutted against the trolley assembly 1. After the lead screw 4 rotates, the push plate 5 is driven to slide on the supporting plate 2.

[0053] In this embodiment, the utility model discloses an auxiliary device for increasing the working node of the handcart, which is mainly used to solve the problem of the switch cabinet handcart in the power system during the sliding in or out process, especially for the switch cabinets of different height specifications and the shortcomings in the uniformity of the force of the handcart. The design of the combination of the lead screw 4 and the push plate 5 realizes the precise control of the movement of the push plate 5. When the lead screw 4 rotates, since the mounting end 7 of the push plate 5 is threadedly arranged on the lead screw 4, it can slide smoothly and accurately along the slide groove 3, so as to push the handcart assembly 1 smoothly and evenly, avoiding the situation that the uneven force that may occur during manual operation causes the handcart to be damaged. The action end 6 of the push plate 5 directly abuts on the handcart assembly 1, and during the sliding process, it can effectively disperse the force, reduce the impact load borne by the handcart, play a role in protecting the handcart and extending its service life, which not only improves the convenience of the handcart at the working node, but also ensures the safety of the operation process, greatly reduces the failure rate of the handcart caused by improper operation, and enhances the stability and work efficiency of the switch cabinet handcart in the power system.

[0054] Furthermore, it also includes:

[0055] A slide rail 8 is provided on the supporting plate 2, and the slide rail 8 is used to communicate with the track in the switch cabinet;

[0056] The trolley assembly 1 has rollers 9 , which are rollingly arranged on the slide rails 8 .

[0057] In this embodiment, this embodiment provides a more specific auxiliary device for increasing the working nodes of the trolley, which is characterized by adding a slide rail 8 structure that matches the track in the switch cabinet to facilitate the smooth sliding of the trolley assembly 1. The support plate 2 is still responsible for carrying the trolley assembly 1. It is not only provided with a slide groove 3 for the sliding of the push plate 5, but also provided with a slide rail 8. The design size and shape of the slide rail 8 are completely matched with the track inside the target switch cabinet, ensuring that the two can be seamlessly connected, thereby ensuring that the trolley assembly 1 can move smoothly between the two systems. The slide rail 8 is firmly mounted on the support plate 2 and connected to the guide rail in the switch cabinet to form a continuous sliding path, which helps to reduce the friction resistance and vibration of the trolley during movement. In addition to the original structure, the trolley assembly 1 is specially configured with rollers 9. These rollers 9 are arranged close to the slide rail 8 and can be rolled on the slide rail 8. Through the rolling cooperation between the rollers 9 and the slide rail 8, the resistance of the trolley when sliding in or out of the trolley cabinet is greatly reduced, and the stability and accuracy of the movement of the trolley are also ensured. When the auxiliary device provided in this embodiment is used, the height of the trolley assembly 1 is first adjusted by driving the push plate 5 through the lead screw 4 so that it is flush with the entrance of the switch cabinet. Then, the trolley assembly 1 is overlapped on the slide rail 8 of the support plate 2 through the roller 9 at the bottom thereof, and the trolley can slide in or out easily, accurately and smoothly through the cooperation between the roller 9 and the track in the switch cabinet. This not only optimizes the working efficiency of the trolley, but also greatly improves the safety of equipment operation.

[0058] Furthermore, it also includes: a height adjustment component 10 arranged on the supporting plate 2, and the height adjustment component 10 is used to adjust the height of the supporting plate 2.

[0059] In this embodiment, as a further technical solution, the sliding of the trolley assembly 1 is supported and guided, and a height adjustment assembly 10 is added below or to the side thereof, which is precisely installed on the support plate 2, and its structure may include but is not limited to a hydraulic lifting mechanism, an electric telescopic rod, a threaded knob adjustment mechanism, or a pneumatic lifting device. The height adjustment assembly 10 is linked with the support plate 2. By operating the assembly, the height of the entire support plate 2 relative to the ground or other reference planes can be flexibly adjusted, so that the trolley assembly 1 on the support plate 2 can be accurately aligned with the track in the switch cabinet of different height specifications. For example, when using the threaded knob adjustment mechanism, by rotating the knob, the built-in screw can be driven up and down, thereby driving the support plate 2 to make fine adjustments or large height changes. When the trolley assembly 1 needs to slide into a higher or lower switch cabinet, it is only necessary to adjust the height of the support plate 2 in advance using the height adjustment assembly 10, and then drive the push plate 5 through the lead screw 4, so that the trolley assembly 1 on the support plate 2 can slide smoothly into or out of the switch cabinet along the slide rail 8 with the help of the roller 9, thereby realizing efficient and safe assistance to the work node of the trolley.

[0060] Furthermore, the height adjustment assembly 10 includes: a plurality of lifting rods 11, and the plurality of lifting rods 11 are all arranged on the supporting plate 2; a plurality of support rods 12, and the support rods 12 are used to be arranged on the ground, and the support rods 12 have a sliding cavity 13, and the lifting rods 11 are slidably arranged in the sliding cavity 13. After the lifting rods 11 slide in the sliding cavity 13, they are used to adjust the height of the supporting plate 2.

[0061] In this embodiment, the auxiliary device adds a height adjustment component 10 on the basis of the support plate 2, and the component mainly includes a lifting rod 11 and a support rod 12. A plurality of lifting rods 11 are provided, and they are all firmly installed at the lower part of the support plate 2. Each lifting rod 11 can act independently or synchronously, and the overall height of the support plate 2 can be changed by telescoping. A plurality of support rods 12 are also provided, and the main function of these support rods 12 is to provide a stable support point on the ground. A sliding cavity 13 is designed inside the support rod 12, and the lifting rod 11 is cleverly embedded in this sliding cavity 13 to achieve sliding fit. In specific operation, when the height of the support plate 2 needs to be adjusted, the lifting rod 11 can be driven manually or electrically to slide up and down in the sliding cavity 13 of the support rod 12. By controlling the extension length of each lifting rod 11, the support plate 2 can be lifted or lowered synchronously, so that the trolley assembly 1 on the support plate 2 can accurately correspond to the rails in the switch cabinet of different heights, so that the trolley assembly 1 can slide in or out smoothly.

[0062] Furthermore, the first clamping groove 15 passes through the first through groove 14 and abuts against the first clamping groove 15. After the first clamping member 17 rotates, it drives or does not drive the lifting rod 11 to slide in the sliding cavity 13. The driving member 19 is arranged on the mounting seat 16, and the driving member 19 is used to drive the first clamping member 17 to rotate.

[0063] In this embodiment, the bottom of the support rod 12 is fixed on the ground, and a sliding cavity 13 is provided inside to accommodate and guide the sliding of the lifting rod 11. A first through groove 14 is also provided on the support rod 12, and the groove is connected to the sliding cavity 13, so as to facilitate the interaction between the card slot structure of the lifting rod 11 and the external components. A plurality of lifting rods 11 are installed at the lower part of the support plate 2, and a plurality of first card slots 15 are distributed on each lifting rod 11. These card slots are connected to the first through groove 14 of the support rod 12, and the precise adjustment of the height is achieved through engagement. The mounting seat 16 is arranged at an appropriate position of the support rod 12, and is used to install and fix other height adjustment components 10. The first clamping member 17 is rotatably arranged on the mounting seat 16, and has a first support end 18. The support end can pass through the first through groove 14 and tightly abut against the first card slot 15 on the lifting rod 11. When the first clamping member 17 rotates, if the contact state between the clamping slot and the support end changes, the lifting rod 11 can be driven to rise or fall in the sliding cavity 13 to adjust the height of the support plate 2. The driving member 19 is fixed on the mounting seat 16, and its function is to drive the first clamping member 17 to rotate. The driving member 19 can be a manual knob, a worm gear structure driven by a motor, or other suitable power source. By operating the driving member 19, the lifting and lowering of the lifting rod 11 can be conveniently and quickly adjusted, and then the height of the support plate 2 and the trolley assembly 1 carried by it can be accurately adjusted. In actual application scenarios, the staff drives the first clamping member 17 to rotate by operating the driving member 19, so that the first supporting end 18 of the first clamping member 17 engages or disengages with the first slot 15 on the lifting rod 11, thereby controlling the lifting rod 11 to slide in the sliding cavity 13 of the support rod 12, and finally achieving precise adjustment of the height of the support plate 2 and the trolley assembly 1, ensuring that the trolley assembly 1 can be smoothly and safely docked with switch cabinets of different height specifications.

[0064] Furthermore, the driving member 19 includes: a rotating member 20 rotatably disposed on the mounting seat 16 , and the first clamping member 17 is rotatably disposed on the mounting seat 16 through the rotating member 20 ; a limiting plate 21 disposed on the rotating member 20 , and the limiting plate 21 is used to limit the rotation of the first clamping member 17 on the rotating member 20 .

[0065] In this embodiment, the driving member 19 of the height adjustment assembly 10 is composed of a rotating member 20 and a limiting plate 21. The rotating member 20 is designed to be rotatably mounted on the mounting seat 16, and the first clamping member 17 indirectly realizes a rotational setting relationship with the mounting seat 16 by connecting with the rotating member 20. When the operator drives the rotating member 20, since the first clamping member 17 is connected to the rotating member 20, it will also rotate along, and the first support end 18 thereon will rotate accordingly along the first clamping groove 15 of the lifting rod 11 in the first through groove 14, thereby driving the lifting rod 11 to slide in the sliding cavity 13 to adjust the height of the support plate 2. In order to ensure the stability of the first clamping member 17 during the rotation process and limit its rotation range, the limiting plate 21 is fixedly set on the rotating member 20. When the first clamping member 17 rotates with the rotating member 20, the limit plate 21 will limit its excessive rotation within a specific angle range, so as to prevent the first clamping member 17 from being disengaged from or over-engaged with the slot of the lifting rod 11 due to excessive rotation, thereby ensuring the accuracy and safety of height adjustment. For example, in actual operation, the staff drives the rotating member 20 manually or electrically, and when the first clamping member 17 contacts the slot of the lifting rod 11 during rotation and generates relative movement, the support plate 2 will rise and fall accordingly. The limit plate 21 plays an effective angle limiting role in this process, ensuring that the first clamping member 17 can only rotate within the allowed range, thereby ensuring the stability of the lifting rod 11 and the accuracy of the height adjustment of the support plate 2.

[0066] Furthermore, the driving member 19 also includes: an articulated rod 22, one end of which is hingedly set on the rotating member 20, and the articulated rod 22 and the first clamping member 17 are respectively located at both ends of the rotating member 20; a foot pedal 23, one end of which is hingedly set on the support rod 12, and the other end is hingedly set to the other end of the articulated rod 22, and after the foot pedal 23 rotates, it is used to drive the articulated rod 22 to move; a first counterweight block 24 is arranged on the foot pedal 23, and the first counterweight block 24 is used to provide force for the foot pedal 23 to rotate.

[0067] In this embodiment, the rotating member 20 drives the first clamping member 17 to rotate, and the first clamping member 17 is connected to one end of the rotating member 20 by hinged connection, and the two together constitute a transmission chain for height adjustment. One end of the hinged rod 22 is hinged to the other end of the rotating member 20, and its function is to convert the movement of the foot pedal 23 into the rotation of the rotating member 20. In this way, when the foot pedal 23 is stepped on, the hinged rod 22 will move accordingly due to the rotation of the foot pedal 23. One end of the foot pedal 23 is hinged to the support rod 12, and the other end is hinged to the other end of the hinged rod 22 to form a lever structure. When the staff steps on the foot pedal 23, the foot pedal 23 will change its angle with the help of its own gravity and the weight of the attached first counterweight 24. The first counterweight 24 is set on the foot pedal 23, and its function is that after the person steps on the foot pedal 23, the foot pedal 23 can be reset under the action of the first counterweight 24. The specific operation process is as follows: when the staff steps on the foot pedal 23 downward, the foot pedal 23 rotates around the hinge point of the support rod 12, and then transmits force through the hinge rod 22 to rotate the rotating member 20. Since the first clamping member 17 is connected to the rotating member 20, it will also rotate with it, and then through the engagement with the first clamping groove 15 on the lifting rod 11, the lifting rod 11 is driven to slide up and down in the sliding cavity 13 of the support rod 12, and finally the height adjustment of the support plate 2 is achieved. This design is more humane, allowing the staff to save effort and be precise during the operation.

[0068] Further, the support rod 12 has a second through slot 25, which is connected to the sliding cavity 13, and the lifting rod 11 has a plurality of second slots 26, which are connected to the second through slots 25 and the second slots 26. The height adjustment assembly 10 also includes:

[0069] A second clamping member 27 is rotatably disposed on the support rod 12. The second clamping member 27 has a second supporting end 28. The second supporting end 28 is used to pass through the second through slot 25 and abut against the second clamping slot 26.

[0070] The second counterweight block 29 is disposed on the second clamping member 27 , and is used to provide a force for the second supporting end 28 to abut against the second clamping groove 26 .

[0071] In this embodiment, on the basis of the original, the support rod 12 is newly provided with a second through slot 25, which is communicated with the sliding cavity 13, in order to cooperate with the second clamping slot 26 on the lifting rod 11. In addition to the existing first clamping slot 15, the lifting rod 11 is also provided with a plurality of second clamping slots 26, which are communicated with the newly opened second through slot 25 of the support rod 12. The second clamping member 27 is designed to be rotatably mounted on the support rod 12, and is provided with a second support end 28. When the second clamping member 27 rotates, its second support end 28 will pass through the second through slot 25 and abut against the second clamping slot 26 of the lifting rod 11. The second counterweight 29 is provided on the second clamping member 27, and its main function is to provide a stable downward force, so that the second support end 28 always has enough force to tightly abut against the second clamping slot 26, so that the lifting rod 11 can be kept stable and motionless at the required height without the need for manual continuous pressure.

[0072] Furthermore, the mass of the second counterweight 29 is greater than the mass of the trolley assembly 1 .

[0073] In this embodiment, based on the above technical solution, in the height adjustment assembly 10, in order to ensure that the second support end 28 on the second clamping member 27 can effectively abut against the second clamping groove 26 of the lifting rod 11 and provide a sufficiently large holding force to counteract the downward sliding tendency of the trolley assembly 1 in any state, the mass of the second counterweight block 29 is specially designed to be greater than the mass of the trolley assembly 1.

[0074] Furthermore, it also includes:

[0075] There are a plurality of toggle rods 30 , which are respectively disposed on the first clamping member 17 and the second clamping member 27 .

[0076] In this embodiment, in order to facilitate the unloading of the first clamping member 17 and the second clamping member 27 by toggling, a toggling rod 30 is provided on the first clamping member 17 and the second clamping member 27 .

[0077] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
